Description
Technical Field
The utility model relates to the technical field of ground screw corrosion prevention, in particular to a ground screw with a sacrificial anode, which has the advantages of simple structure, good corrosion prevention effect, low manufacturing cost, low installation cost and long service life.
Background
As is well known, the sacrificial anode cathodic protection method is a common corrosion protection method for metal structures, has the advantages of simplicity, reliability, low cost, no maintenance and the like, and is widely applied to corrosion protection of various steel structures in seawater environment and soil environment. In the soil environment, the conventional buried sacrificial anode needs to be installed by digging out a buried pit separately, and then filling the buried pit into the sacrificial anode. The ground screw is screwed in once to realize quick installation, and the traditional sacrificial anode installation mode cannot meet the characteristic requirement of quick installation of the ground screw. The existing hoop anode is also not suitable for ground screw installation. Because of the connection mode of the anchor ear, the hoop type anode can not slide in the installation of the ground screw, which is not only unfavorable for fixing the position, but also scratches the surface coating of the ground screw. With the occurrence of corrosion, a gap is possibly generated between the sacrificial anode and the ground screw, and the protection effect of the sacrificial anode is affected. Because a plurality of anchor clamps or bolts are needed to be fixed, the manufacturing cost and the installation cost of the hoop type anode are high, the use of the hoop type anode is limited, the installation cost is high, the manufacturing cost is high, and the service life of a final screw is short.

Detailed Description
The utility model is further described below with reference to the accompanying drawings:
as shown in the drawing, the ground screw with the sacrificial anode is provided with a ground screw body 1, and is characterized in that an annular sacrificial anode body 2 is arranged at the upper part or the middle part of the ground screw body 1, and the annular sacrificial anode body 2 is connected with the ground screw body 1 in a fusion casting mode.
Further, the annular sacrificial anode body is internally provided with the diversion carbon steel plate 3, one end of the diversion carbon steel plate 3 stretches into the annular sacrificial anode body 2, the other end of the diversion carbon steel plate 3 stretches out, and the diversion carbon steel plate 3 stretching out of the sacrificial anode body 2 is welded on the ground screw body 1.
Further, the diversion carbon steel plate 3 extending out of the sacrificial anode body 2 is connected with the ground screw body 1 through a cable wire 4.
Further, the part of the ground screw body 1 where the sacrificial anode body 2 is arranged is provided with a connecting protrusion or a connecting groove or an uneven friction surface, the melted sacrificial anode body 2 is connected with the connecting protrusion or the connecting groove or the uneven friction surface on the ground screw body 1 after being molded, and the connection tightness between the sacrificial anode body 2 and the ground screw is increased.
Further, the connection protrusion 5 or the connection groove is in a ring shape, so that the connection tightness between the sacrificial anode body and the ground screw is further improved.
The above-mentioned adoption melt casting mode is connected between ground screw body 1 and the sacrificial anode body 2, can be inseparabler with being connected between sacrificial anode body 2 and the ground screw body 1, in the downtake of ground screw get into earth the in-process, sacrificial anode body 2 can not break away from with ground screw body 1, be difficult for droing, and owing to be equipped with water conservancy diversion carbon steel sheet 3 in the sacrificial anode body 2, the upper end of water conservancy diversion carbon steel sheet 3 stretches out fixed connection between sacrificial anode body 2 and the ground screw body 1, because the corruption produces the clearance between sacrificial anode body 2 and the ground screw body 1, at this moment, sacrificial anode still is connected with ground screw body 1 through water conservancy diversion carbon steel sheet 3, then sacrificial anode body 2 still continues to function, consequently, the life-span of sacrificial anode body 2 of this patent is longer, above-mentioned ground screw body 1 include the body of rod, helical blade twines on the body of rod or middle part of the body of rod of sacrificial anode body that is equipped with helical blade top.
